Atmospheric pollution emission reduction system for urban overhead

The invention provides a city elevated atmospheric pollution emission reduction system, and relates to the field of road environmental protection, the city elevated atmospheric pollution emission reduction system comprises a support bottom plate, leaf-shaped nozzles, an atomization spray pipe, an arc pipe and a functional support rod, the upper end surface of the support bottom plate is provided with a mounting cavity with an upward opening, and the inner lower wall of the mounting cavity is fixedly provided with a filling column, and the filling column is in a halfpace shape. According to the scheme, the leaf-shaped spray heads are arranged in a staggered mode, so that the leaf-shaped spray heads present a staggered layer feeling, the whole body is more mimicry, the ornamental value is greatly improved, and the visual impact on a vehicle driver is reduced; according to the system, the atomization spraying mode is adopted, the coverage range of atomization spraying is expanded, then the follow-up atmosphere e
